NT-Pro BNP
Understanding NT-Pro BNP
What is NT-Pro BNP?
NT-Pro BNP test is used to measure the amount of BNP (B-Type Natriuretic peptide) and NT-Pro BNP (N-Terminal-Pro) in the blood. These molecules are released into the blood stream in response to any stress encountered by the heart. Elevated level of these molecules is an indicator of excessive pressure on heart, heart faliure, or other acute heart conditions.
This test is recommended generally after a heart attack or to those undergoing any heart disease treatment.
A normal value of NT-Pro-BNP should be under 100pg/mL. Any value higher than this is considered fatal and an immediate medical intervention is mandatory.
What is NT-Pro BNP used for?
The NT-Pro BNP test is done to help in the detection, diagnosis, and evaluation of the severity of congestive heart failure (CHF).

In case of congestive failure in first hour or in case of ventricular inflow obstruction, there is lack of rise of N-terminal pro-BNP levels.
